Hi,
Regarding the answers to this question, would you do something differently if your hens had fewer feathers on their necks? Ours have been kinda hard on each other and in particular the silkies are pretty bald around their waddles, so I worry about no heat in that scenario? (regarding the pecking, we've been trying a lot of different things... I don't think we have any single problem bird and they all seem to be losing feathers also. Treated for mites, have increased protein and calcium sources, have put up pecking balls... any other suggestions welcome.) Our birds free range during the day, have a smaller coop with a sheltered run, we are in Oregon, probably the lowest temperature we'd see is -5F.
Thanks!
